Improved shade-hook



STATES.

PATENT SAMUEL WHITE, OF PHILADELPHIA, PENNSYLVANIA.

iMPROvl-:D'SHADE-HOOK.

To all whom t may concern:

Be it known that I, SAMUEL WHITE, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedShade-Hook; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled intheart to make and use the same, reference being had to the accompanyingdrawings, forming a part Ot' this specification, in which- Figure I is aside elevation of my invention. Fig. 2 is a top view, the screw-rodbeing cut Oft' on the line w x, Fig. l.

Similar letters of reference indicate like parts.

This invention is designed for holding and keeping taut the cord whichisused for drawing up window-shades.

My invention consists in the employment of a suitable screw-socketcarryin g a screw or the like for enabling it to be secured to the frameof awindow, and a screw-rod which passes through said socket, which hasa hook upon one end, and is provided, as regards the other, with a nut,by which the rod can be thrown up or let down for loosening ortightening the cord, as occasion may require.l

A designates the socket, and this may be of any appropriate form. In thepresent instance it is spherical, having a neck, a, terminating in aplate-like portion, b, with a flat face, which, when the device isapplied, rests against the frame of the window. A screw, o, projects outfrom the face Of the plate for securing the device to the window-frame.

Bis the screw-rod which passes through the spherical'portion of thesocket A, and is Operated by a nut, d, upon its lower end, which worksupon the screw. The upper end, of the screw-rod is in the form ot' ahook, c, and this is caught over the cord employed for raising aroller-curtain, as shown in Fig. 1. The screwrod has squared sides, thescrew-thread for the uut to work on being cnt on the corners. This rodpasses through a square socket, which, of course, has squared sides, andit cannot therefore revolve, as might Occur were it round; and it can bemoved up or down in the socket without difficulty.

It is well known that the cords employed for raising rollercurtainsafter awhile become slack, and the commonest of the devices used fortightening them so that they will operate properly is a slide working ina toothed rack which is secured to the window-frame, the cord beingthrown over a button connected to the said slide. The tension Of thecord is regulated by adjusting the slide to thedevised tooth on therack. These racks'are not as efficient as they should be in very manyrespects.

Now, it will be observed by my device the tension of the cord may beregulated by merely turning the nut d. The device is at Once simple',and provides a greater length for the screwrod for tightening the cordwhen it has become quite strained. This cannot be done with the devicealluded to in so great a degree with- Out making the rack so long as tobe unsightly, or by taking it Off and securing it again lower down onthe window-frame, or putting on a new cord.

My device is simple, and will accomplish all that is required of it, andit is susceptible of being made as ornamental as desired.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the socket A, screw-rod B, and nut d, the sameconstituting an improved device t'or holding and regulatingthe tensionoi' the cords used for raising w1ndowshades.
